Optimization of Vanillin Synthesis from Glyoxylic Acid

摘要:

采用乙醛酸工艺研究了甲基香兰素的合成方法，讨论了3-甲氧基-4-羟基苯乙醇酸、3-甲氧基-4-羟基扁桃酸制备中温度、物料比、催化剂、压力对产率的影响，通过选择合适的反应条件，可以提高香兰素的得率。

Abstract:

Synthesis of vanillin from guaiacol and glyoxylic acid was investigated. The effects of temperature, proportion of reactant, catalyst, and pressure on the yields of the resulting mandelic acid to the corresponding phenylgyoxylic acid were studied. High se
